Title: Effective Piezoelectric Coefficients $$d_{ij}^{*}$$: From Microgeometry to Anisotropy
Abstract: Piezoelectric coefficients dij are most widespread to describe the piezoelectric effect, electromechanical properties and other related parameters. The effective piezoelectric coefficients $$d_{ij}^{*}$$ and their links to sensitivity are discussed for piezo-active composites with various connectivity patterns. Examples of the piezoelectric sensitivity of the 2–2-type, 1–3-type, 1–1-type, 0–3-type, and 3–β composites based on ferroelectics are considered. The role of the microgeometry in forming the piezoelectric sensitivity and anisotropy of the piezoelectric coefficients $$d_{3j}^{*}$$ is analysed. Ways to improve the piezoelectric sensitivity in terms of $$d_{ij}^{*}$$ are discussed in connection with potential piezotechnical applications.
